I would like a UI design, that works with the visually impaired users, they should be able to zoom in the app and enlarge tabs and stuff, also inverting the colors for the color-blind people, etc. - As well as a standard version of the app.
There will be:
Social features (Blog, News)
Live streaming through youtube
A list of training programs page.
The design should take into consideration that it will be integrated with apple's text-to-speech and accessibility features for the special needs segment/users.
